Description

Unmanned transport vehicle

Technical Field

The utility model relates to the technical field of unmanned transportation, in particular to an unmanned transport vehicle.

Background

An automatic charging system is additionally arranged on an existing unmanned transport Vehicle (AGV), the unmanned transport Vehicle can automatically monitor the electric quantity of a battery pack, automatically search charging piles installed in a field when charging is needed, and automatically butt a charging device and an external charging pile to realize a charging process. The manual charging operation is omitted, and the use efficiency of the whole factory unmanned transport vehicle can be improved.

Optimization of unmanned vehicles is helping industrial environments remain competitive in today's market, enabling them to meet the needs of customization and rapid delivery, while reducing labor costs.

Wireless charging systems use magnetic fields to transfer energy from a charging source board installed in a factory floor to a receiving board installed on an unmanned transport vehicle. Modern wireless charging systems based on magnetic resonance principles have proven to be safe, maintenance free, efficient, and can be charged as fast as traditional wired chargers. A technical advantage of wireless charging is that no mechanical or electrical contact is required between the charging source and the unmanned transport vehicle. This brings significant advantages and cost savings.

By replacing the labor intensive and failure prone plug-in charging and battery replacement processes with autonomous wireless charging systems, the industrial environment can fully realize the benefits of its investment in advanced unmanned transport vehicle technology. These are immediate and far away, including: productivity, vehicle availability and safety are improved. A conventional process of charging a mobile robot or an unmanned transport vehicle or the like is to stop a vehicle for charging. For all weather operated plants and warehouses without "off duty", this means that the number of unmanned vehicles operating must be greater than the number of unmanned vehicles that need to be charged, or many unmanned vehicles will stop operating at any given time waiting to be charged. In addition, it is common that the labor intensity of inserting and extracting the vehicle from the charger is large. Both of these factors add to the total cost of ownership of the unmanned transport vehicle and run counter to the 24/7 "light-off automation required by industry 4.0. Some manufacturers have developed and used extended charging ports to enable unmanned vehicles to "plug" into the charging post via specially designed electrical connectors. Such equipment requires frequent maintenance, can damage the electrical connectors due to repeated mating and docking operations, and can lead to serious safety concerns.

Automatic wireless charging may improve the productivity, usability, and safety of unmanned transport vehicle systems. Unmanned transport vehicles equipped with modern wireless charging technology based on magnetic resonance can achieve so-called opportunistic charging. For example, unmanned vehicles with relatively low power can be charged when the charging pile is idle. Modern wireless charging solutions do not require accurate positioning of the robot, so charging can begin as long as the robot remains a reasonable distance from the charging pad. This charging function allows charging to be performed anytime and anywhere without having to stop using for hours after charging, which allows an operator to minimize the number of robots required for a service facility. Maintenance costs may also be reduced by eliminating the need to repair and replace worn connectors and cables. Frequent opportunistic charging will prevent the battery from being completely depleted, thereby extending the useful life of the battery pack.

However, in the operation environment of factory, need install the electric pile that fills that charges for unmanned transport vechicle is wireless additional, and the electric pile that fills that adorns afterwards is mostly for protruding ground setting, and unmanned transport vechicle when with fill electric pile butt joint, the wireless charging structure of unmanned transport vechicle easily with fill electric pile and bump, lead to wireless charging structure's damage.
